Hello!

Answer:

n=-9

*The answer must have a negative sign.*

Step-by-step explanation:

First, you subtract by 7 from both sides of an equation.

$7+2n-7=-11-7$

Then, you simplify.

$2n=-18$

Next, you divide by 2 from both sides of an equation.

$\frac{2n}{2}=\frac{-18}{2}$

And finally, simplify and solve. You can also dividing into the groups.

$18/2=9$

$n=-9$

Hope this helps!

Have a great day!

If the function f (x) is defined by f(x) =x over 2 minus 6

Tema [17]

Depending on how it is written, it could be either of these following solutions:

f(x) = x/2 - 6 or f(x) = x/(2-6)

For the first, we solve for x by replacing f(x) with 0

x/2 - 6 = 0

x/2 = 6

x = 3

For the second, do the same

x/(2-6) = 0

x/-4 = 0

x = 0
